Portland 2026 rules
For 2026, the Oregon standard rent limit checked by RentCap is 9.5%. Portland adds relocation-assistance consequences when an increase reaches 10% or more within a rolling 12-month period, so the percentage and bedroom count both matter.

For landlords
Check the increase before delivery. The packet keeps the statewide cap, Oregon mail timing, and Portland relocation path separate and uses the bedroom count only when the local payment schedule matters.
For renters
Enter the rent, delivery method, effective date, and bedroom count from the notice. The result flags statewide cap, mail timing, and Portland relocation questions separately.
What to enter
Use the exact current rent, proposed new rent, planned delivery date, delivery method, property type, tenancy type, and any exemption facts. ZIP code is optional, but it helps apply Seattle, Tacoma, and Portland rules.

Portland amount check
The amount check starts with the current monthly rent and the proposed new rent. RentCap calculates the percentage increase, compares it with the published Oregon limit, and keeps exemption questions separate so a missing fact does not look like a clean pass.
Portland timing check
Oregon notice timing and delivery rules decide the earliest supported effective date. The checker also aligns monthly increases to the rent-period start day entered in the form, because a day-count minimum can land mid-cycle.
City rules
Portland can require local rights language and relocation assistance when an increase reaches 10% or more within a rolling 12-month period. ZIP code is used as a backup for the cities RentCap covers, which helps avoid a wrong answer when the city name is misspelled or abbreviated.
